What Color Is Safety?
The color of anything depends on the type of light sent to our eyes. An object is "colored," because of the light it reflects – all other colors are absorbed into that specific object. So, an apple appears red because it reflects red light. White light from the sun contains all the possible visible color variations.

The primary colors of light are red, blue and green. These occur in the Additive Color (RGB) Model, so named because black is the base and light is "added" to eventually get to white, which is all of the colors together. Additive colors are seen in televisions, nature, and the computer screen. Amazingly enough, colors are perceived in our eyes and brains by a three-color code; three different particles in the retina are sensitive to red, blue, and green. Just as any color of the spectrum can be made by mixing the three primary colors, so do our own eyes discern the various colors by sensing and mixing colors in these three receptors.Back to News//
